First Claim
Patent Images
1. The process for fastening a cap to a container, which cap and container are provided with engaging structure cooperating for the purpose of fastening, the process comprising the steps of:
- positioning the container and the cap in a starting position in relation to one another by holding a cap with a clamping grip during the positioning;
connecting a non-clamping holding device to the cap;
releasing the clamping grip of the cap after positioning;
subsequent to said step of releasing the clamping grip, connecting the cap to the container whereby the cap is held as the container is moved, or the cap is moved relative to the container by the connection of the non-clamping holding device to the cap, up to a desired tightening torque.

Abstract
During the fastening of a cap (2) on a container (1), the container (1) and the cap (2) are positioned in a starting position in relation to one another and subsequently connected to one another in a positive-locking and preferably also non-positive manner. The cap (2) is held during the positioning by a clamping grip. The positioned cap (2) is taken over by a non-clamping holding mechanism (5), and the clamping grip of the cap (2) is released before the positive-locking and preferably also non-positive connection.

3. A device for fastening a cap on a container, which container and cap are provided with engaging means cooperating for the purpose of fastening, the device comprising:
-
a positioning means for positioning the container;
a holding and positioning means with a clamping holding means, which clampingly holds the cap and positions same in a starting position in relation to said container, said clamping holding means engaging the cap to connect the cap to the container in a positive-locking manner and said holding and positioning means also including a non-clamping holding means movable in relation to said clamping holding means, said non-clamping holding means connecting said cap to said container by a forced relative movement, said non-clamping holding means including a contact piece in contact with said cap and a friction coupling that is engagable and disengagable with said contact piece to hold said contact piece up to a defined frictional force between said contact piece and said friction coupling.

11. A device for fastening a cap with a thread fastening portion on to a container with a corresponding cooperating thread fastening portion to be engaged with the cap fastening portion, the device comprising:
-
a container holding positioner for positioning of the container or for rotating the container in a position relative to the held cap;
a cap holding and positioning device for positioning the cap or for rotating the cap in a position relative to the held container including;
a clamping device for clamping contact with the sidewall of the cap for initially positioning the cap;
a contact device with a contact element contacting a top surface of the cap for holding the cap during relative rotation of the cap and container for fastening together the cap thread fastening portion to the container thread fastening portion and with a support connection part for rotating or holding the contact element, said contact device being holdable of the cap after said clamping device releases the cap in order for the contact device to rotate the cap onto the container. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
said contact device is movable away from said clamping device while said contact device is holding the cap and the cap is released by said clamping device.
